Your Shoulder is a Digger| Ep. 27

Imagine an excavator working while anchored into a soft muddy surface. Now imagine that same excavator working with its tracks anchored into concrete. Which do you think would be more efficient? Which do you think would be able to apply more power into digging? Which do you think would break more often?

These answers should be unanimous. The excavator anchored into concrete is more sturdy therefore can apply more force with its bucket. Sturdiness provides stability and reduces torque on the excavator arm so its less likely to break. Obviously the previous two answers imply its more efficient.

Your shoulder blade (scapula) can be thought of as the cab (the big square part that people sit in!) of the excavator. When we leave our scapular stabilizers flaccid the shoulder blade is pushed around by the forces of the arm… we are working in the mud! When the scapular stabilizers are contracted it is like anchoring the tracks in concrete. The cab (scapula) no longer gets pushed around. The results, your arm can apply more power, has reduced torque, is more efficient, and gets injured less. Mind Blown!!!
